WARPER.

Specification of Letters Patent.

Patented May 14:, 1912.

Application filed February 2,: 1912. Serial No. 674,990.

county of Stra'flord, State of New Hampshire, have invented an Improvement in W'arpers, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention has for its object the production of'simple and effective means for clearing away and removing the lint or flufi which collects in a warper as the warpthreads travel through the usual'drop-wires and reed on their way to the beam. As the threads travel through the eyes of the dropwires the loose particles of lint are scraped off and deposited upon the drop-wires and their support, the lint'collecting to such an extent that it not only clogs the wires but may also be picked up and carried along in small bunches by the warp-threads, such deposition and collecting of lint also occurring at the reed, or reeds, when two are used. Heretofore it has been necessary for the warper attendant to remove these collections of lint from time to time, and this is rendered diflicult because the lint collects beneath the sheet of warp, so that when a light stick or rod is used to remove the lint, (a common practice) the warp-threads are sometimes caught and broken, and at best the removal of the lint is slow and inefli cient, and sometimes necessitates stoppage of the warper.

Our present invention comprehends means to effect automatically the removal of the lint from those portions of the warper where it collects in objectionable quantities, and herein we have provided simple and efiicient means for taking up and removing the lint from the vicinity of the reed and drop-wires.

The various novel features of our invention will be fully described in the subjoined specification and particularly pointed out in the following claims. 7

Figure 1 is a side elevation of a suflicient portion of a warper, with one practical embodiment of our present invent-ion applied thereto, numerous usual parts of the warper not necessary to a proper understanding of our invention being omitted; Fig. 2 is a top plan view,-centrally broken out, ofthe ap paratus shown in Fig. 1, in so far as it relates to our invention, to illustrate clearly the construction and arrangement of the lint clearing means; Fig. 3 is a detail in front elevation of the means whereby the movement of one clearer is transmitted to the other clearer, as will be explained; Fig. 4L is a perspective View, enlarged, of the detachable brush which may be used for conveniently stripping or' cleaning the collected lint from the clearer.

the driving shaft 2, (shown in section, Fig.

1,) the shaft 3 which drives the usual drum,

not shown, for winding the warp onto the beam 4, the front and back reeds 5, 6

through which the warpthreads 7 travel, the guide-roll 8, tensioh rolls 9, 9, 9 for the sheet of warp, and the transverse supports or bars l0, 10 on which the two series of drop-wires 11 are pivotally mounted, the parts referred to being all of well known construction and in themselves forming no part of our invention. The drop-wires are pivoted at their lower ends 011 the supports 10, at the back of the latter, the eyes 12 of said drop-wires receiving the warpthreads, and the forward travel of the latter tends to draw the wires forward with the eyes overhanging the supports, as shown best in Fig. 1. As the sheet of warp passes through the warper a considerable amount of fluff or lint is removed from the threads by the drop-wires and by the reeds, and

such lint collects 011 the supports 10 adjacent the drop-wires and also on and adjacent the reeds. Such deposited lint must be removed from time to time or it will clog and prevent the proper operation of the drop-wires when'a thread breaks, and it also clogs the teeth of the reeds, so that there is a tendency to carry small bunches of lint along with thethreads to the beam. This lint, in accordance with ourpresent invention, is cleared or removed automatically from the points where it collects, as will now be described. y

In accordance with the illustrated embodiment of our invent-ion we attach fixedly to a rotating member of the warper, as the shaft 3, a peripherally grooved sheave 18, around which is passed the bight of an end less flexible clearer 14:, having a roughened like band of slack-twisted cotton is highly efficient. The sides of the bight of said clearer extend upward from the driving sheave 13 and are carried over two. parallel guide sheaves 15, 15 mounted to rotate 011 horizontal axes sustained by a suitable bracket 16 attached to the left hand side 1 of the warper frame, Figs. 1 and 2. These guide sheaves are so located that the parallel runs 17 18, Fig. 2, of the clearer will travel above the two supports 10 very close to the same and to the eyes 12 of the two series of drop-wires, but in opposite directions,.and in horizontal paths across the top of the warper, but below the sheet of warp 7.

On the right hand frame 1 is bolted a bracket 19, Figs. 2 and 3, which sustains a vertical stud 20 on which is rotatably mounted a horizontal guide sheave 21 around which the clearer 14 is carried, the longitudinal movement imparted to said clearer by the driving sheave 13 causing the sheave 21 to be rotated. Now as the clearer runs 17 and 18 move along adjacent the two series of drop-wires the collected lint is picked up by the roughened surface of the clearer and carried along thereby away from the vicinity of the drop-wires, so that the latter are kept clear and clogging is prevented. The lint adhering to the clearer can be removed from time to time as may be necessary, in any suitable manner, either by stripping the clearer by the hand of the attendant, or by mechanical means. Herein we have shown a mechanical stripper, as a brush 22, the back 23 of which, see Fig. 1, is detachably held preferably in spring clips 24, fastened to the warper side, the clearer traveling over and in contact with the ends of the bristles forming the brush. This stripper brush can be located at any convenient place on the warper, and in Fig. 1 we have shown it so located as to cooperate with the clearer 14: as the latter moves toward the driving sheaves 13, but it will be understood that any other desired location may be used. The sheave 21 has attached to it a larger grooved sheave 25, and an adjustable arm 26 on the stud 20 carries a small tension sheave 27, Figs. 2 and 3.

Referring now to Fig. 2, brackets 28 are extended laterally from the frame sides and carry horizontal guide sheaves 29 so located that a tangent to their peripheries will pass just back of and adjacent the back reed 6 adjacent the lower ends of the teeth thereof. A similar bracket 30 at the front of the frame carries a horizontal guide sheave 31, so located that a tangent to it and the large sheave 25 will pass behind and adjacent the lower ends of the teeth of the front reed 5.

An endless reed-clearer 82 is passed around the sheave 25 and the three guide sheaves 29, 31, as clearly shown in Fig. 2,

and the tension sheave 27 is set against said clearer to impart the desired tension thereto. The parallel transverse runs 33, 34L of the clearer 32 thus travel, in opposite directions, across the top of the warper, below the sheet of warp and adjacent the front and back reeds 5, 6 respectively, and as lint collects in the vicinity of the reeds it is taken up and removed by the adjacent portions of said clearer, the reed-clearer being a ropelike member like the clearer for the dropwires, previously described. The longitudinal movement of the reed-clearer is effected by rotation of the sheave 25, as will be apparent, so that indirectly the reed-clearer is driven by or through the drop-wire clearer through the agency of the attached sheaves 21 and 25.

e have not shown any stripping brush for the reed-clearer, as the latter can be very easily stripped by hand, but if desired a stripper brush such as previously described for the drop-wire clearer can be used for the reedclearer, and located in any convenient place, as for instance on either of the brackets 28 or 30.

By our invention we dispense with the use of a stick or other device poked under the warp-threads along the drop-wires or reeds, and hence obviate any tendency to injure the warp or the adjuncts of the warper, '4

Various changes or modifications in details of construction and arrangement may be made by those skilled in the art without departing from the spirit and scope of our invention as set forth in the claims hereto annexed.

Having fully described our invention, what we claim as new and desire to secure by Letters Patent is:

l. The combination, in a warper having a series of drop-wires provided with eyes through which the warp-threads travel, and a fixed support for the said drop-wires and above which their eyes are held by intact warp-threads, of a flexible, rough-surfaced and ropelike endless clearer band, means to sustain a portion thereof immediately above the support for and adjacent the eyes of the drop-wires but below the sheet of warpthreads, and means to effect a continuous longitudinal movement of said clearer band in one direction whereby that portion therespectively, and means actuated by a moving.

part of the warper to effect continuous longitudinal movement of the clearer, whereby movement of the latter past the drop-wires takes up and clearsaway the lint deposited in the vicinity of the drop-wires.

3. In a warper, two series of drop-wires having eyes through which the warp-threads travel and arranged in parallelism, an endless flexible clearer having a rough surface, means to support opposite y moving runs of the clearer adjacent the eyes of the two series of drop-wires and below the warpthreads, means to efiect continuous longitudinal movement of the clearer, to take up and carry away from the drop-wires the lint deposited adjacent thereto, and a brush across which the clearer travels, to clean the lint therefrom.

4. In a warper front and back reeds through which the warp-threads pass, a series of drop-Wires between the reed and cooperating with intact warp-threads, an endless, flexible clearer movable for a part of its length in a path below the warpthreads and adjacent the drop-wires, to collect and remove lint deposited adjacent thereto, a rotatable sheave around which the clearer travels, a second, attached sheave, a second endless clearer traveling around it, means to support the said clearer with two portions thereof adjacent the front and back reeds, respectively, to clear the deposited lint therefrom, and means to effect continuous longitudinal movement of the drop-wire clearer, cooperation thereof with the first sheave effecting longitudinal movement of the reed clearer through the second sheave.

5. In a warper, a reed for the warpthreads, a series of drop-wires cooperating of drop-wires with intact threads, a clearer to take up and remove lint deposited adjacent the dropwires, a second clearer operating in like manner for the reed, means to eflect operative movement of one of the clearers, and means to effect operative movement of the other clearer by or through the first-mentioned clearer.

6. In a warper, a reed for the warpthreads, a series of drop-wires cooperating with intact threads, an endless, flexible clearer having a roughened surface and movable longitudinally adjacent the dropwires, to collect and remove lint deposited adjacent thereto, a second similar clearer movable longitudinally adjacent the reed to collect and remove lint therefrom, means to drive one of said clearers, and means to drive the other clearer by or through longitudinal movement of the first one.

7. In a warper having a reed through which the warp-threads travel, and a series cooperating with intact threads, in combination, two clearers operating automatically adjacent said reed and drop-wires, respectively, and beneath the sheet of warp, to take up and remove the lint collecting adjacent the reed and drop-wires, and means to eflect the operation of the clearers.
